1o clama (ci. :sa-ss) This invention relates to a recording mechanism, for sales computing and indicating registers, and particularly to one for use in connection with aliquid dispensing pump of the clock type.

The present application also is a continuation in part of my application on recording and invoicing device for liquid dispensing pumps, Serial No. 537,846, led May 16, 193i.

When incorporated in a liquid dispensing pump the device will enable a visual record of the actual quantity of liquid dispensed to be presented to any customer, so that he may not only be sure that he has obtained full measure, but will have a permanent record of the transaction.

The principal object of my invention is to provide a device of this character adapted to use a long strip of recording paper printed in the form of blank tickets spaced lengthwise along the strip. and constructed so that with a single turning operation of a hand shaft through a predetermined arc (preferably one full revolution) the ticket will be stamped at the proper place, the stamping device returned to its initial inactive position, and the strip advanced the length of a. ticket. This last movement advances the stamped ticket so that it is accessible to the operatorv for tearing .from the remainder of the strip for presentation to the customer.

At the same time, a duplicate ticket is automatically stamped and retained in the machine for the records of the owner or operator.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly eiective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as Y will fully appear by a perusal of lthe following specification. l

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a sectional elevation of my improved recording mechanism, showing the position of the parts in their normal position o r prior to a strip impressing and advancing operation.

Figure 2 is a similar view showing the position of the parts just as the punch or impressing device is being operated.

Figure 3 is a plan view of a blank invoice ticket, detached from the strip.

Referring now more particularly to the characters of reference on the drawings, the device comprises a housing fragmentarily illustrated at I in which is mounted a platform 2 having a continuous circular slot or groove 3 therein. A supply of paper l is supported in the casing below the platform, the supply being made in the form of at least two superimposed strips, an outer one 5 andan under one B. Both strips are printed in theform of longitudinally extending blank invoice tickets I as shown in Fig. 3, the outer strip being preferably rouletted or otherwise weakened for easy tearing between adjacent tickets as indicated at 8. The under surface of the strip 6 is carboned so that an impression of any writing thereon will be transferred to the under strip.

From the supply, the strips pass between upper and lower feed rolls 9 and I0 respectively, disposed adjacent one end of the platform. The strips then pass over the platform, the upper one 5 projecting through a. slot ll in the casing parallel to and adjacent the level of the platform, and the under strip 6 also passing through said slot and then reentering the casing through a lower slot i 2 and being then wound on a removable take up spool I3 inc unted in the same man ner as a camera take up spool/By reason of this arrangement, an outer ticket may be written'on when projected through the casing and the writing will be impressed on the corresponding ticket of the under strip.

The lower feed roll i0 carries a -pinion il positioned to engage a mutilated gear I5 fixed on a hand shaft I6, the ratio of the gear and pinion relative to the size of the feed roll and the length of the ticket' being such that with each full revoiution of the hand shaft, the strips will be ad vanced along the platform exactly the length of one ticket. A siip-belt drive i1 connects the roll I0 and the take-up spool. The ratio of the belt drive relative to the speed of the feed roll is such that when 'the spool is empty, a full revolution of the hand shaft is just suicient to wind the same length of paper thereon "as is advanced by the feed roll. As the spool rolls up, a lesser amount of rotation of the same is of course nec-` essary to wind said length of paper thereon. The belt then slips and merely holds the paper snugly wrapped about the spool.

Projecting upwardly from above the platform lconcentric with the slot 3 is a vertical shaft I8. This is adapted to be rotated through a full turn or less with the operation of the 'apparatus in which the recording mechanism is installed by a gear connection I9 with a driven shaft 20. Each ticket has a circular dial 2| printed thereon and I marked to indicate different quantities (such as gallons). This dial is substantially the same diameter as slot 3 and is disposed on the ticket so that when the latter is on the platform at the end of a strip advancing operation, the dial is centered with the slot.

Slidably but non-turnably mounted on the lower end of shaft I8 is a sleeve 22 having a. radial arm 23 projecting from its lower end. A punch 24 depends from this arm in line with slot 3, but normally above the platform and paper.

Above the arm the sleeve has a flange 25 engaged by the bifurcated end of the adjacent leg 26 of a bell crank unit which is turnably pivoted above the platform on a cross shaft 21. The other leg 26d of the bell crank depends on one side of the platform and rides on a cam 28 secured on shaft I6.

The cam 28 is arranged so that the bellI crank Will be maintained idle andthe sleeve held lifted except at a certain point R on the cam which is raised sufficient to cause the bell crank arm 26a to be lifted and the sleeve to be depressed so that the punch will perforate the ticket resting on the platform, as indicated at P in Fig. 3. The raise R occupies a predetermined position relative to the mutilated portion of the gear l5 as will be seen.

The end of each printed ticket, to the sides of the dial thereon, is provided with a pair of holes 29 which, when the dial on the invoice is concentric with the punch shaft i8, registers with openings 3b in the platform. Vertical iingers 3l alined with the openings 30 are mounted above the platform as a unit with a vertically movable guided frame 32. The bottom of this frame is normally engaged and held raised by one end of a pivoted lever 33 which in turn is engaged and normally prevented from dropping by the upturned end of the arm 34` pivoted in a xed position at one end above the shaft i6. This arm isl formed with a depending latch element 35. This normally rides on the circular portion of another cam on the shaft lli, the lever 33 and the ringer being then held raised. The cam however is formed with a notch N adapted to receive the latch element 35, at which time theA arm, lever and nger are lowered. to cause the ngersto project through the openings 29 and 3d, and thus positively hold the paper in a centered position and against movement ready to be punched.

This notch N is arranged so that the nger dropping operation takes place at the completion of a punching, paper feed, and punch re setting cycle. Also the latch element engaging in the notch enables the operator to tell, by the feel, that such cycle of operations is completed and the structure ready for another liquid dispensing operation. The notch is also positioned just ahead of the punch controlling cam raise R, so that upon the Subsequent rotation of the handle from its latched position the punching operation is performed almost immediately.

To reset the punch, another gear 3l is mounted to mesh with the mutilated gear and which gear 3l, for convenience of assembly, is mount ed on the shaft 2li but has no connection with the punch operating bell crank. A slip drive 3b connects this gear with the shaft il@ of the machine.

Prior to operating the pump or other struc ture to dispense liquid the parts of the recording or control mechanism are as shown in Fig. In other words, the paper holding iingers 3i are lowered, (passing through holes 2i) in the adjacent ticket) the punch sleeve 22 is raised and the gear dlrand pinion l@ are both clear of the teeth of the gear I5. When the shaft 20 is then rotated with the operation of the machine, the punch arm is rotated about the invoice dial to a position corresponding to the amount of liquid dispensed. While the gear 31 will then be rotated due to its driving connection with the rotating shaft 20, no rotation will be imparted to the gear l5 since the teeth of said gears are not then in engagement.

When the dispensing operation is halted the operator Writes whatever is necessary on the portion of the ticket about to be punched and which already projects somewhat from the casing and rotates the shaft i6 in the direction indicated by the arrow. 'Ihis causes the cam raise R to drop the bell crank arm 2S and cause the punch to be depressed as shown in Fig. 2, perforating the ticket dial as indicated at P in Fig. 3. With a slight further rotation of the crank handle the punch is raised and at the same time the fingers 3l are also raised clear of the ticket by the movement of the cam 36 relative to the latch element 35, causing the latter to bemoved out of the notch N. The teeth of the gear l5 then engage the teeth of the gear 3l and impart rotation in the resetting direction to the shaft 20 and thence punch shaft I8.

Shortly after the gear l5 engages the gear 37, it also engages the pinion I4, feeding the paper along the platform to dispose a fresh ticket under the punch and causing the ticket just punched to be projected from the casing of the apparatus in position to be grasped and torn olf by the operator. Just before the hand shaft i6 has completed a'full revolution the teeth of the gear i5 leave the pinion M. A further feeding of the paper is thus halted so that when the holding ngers 3l are dropped by the engage ment of the latch 35 in the notch N at the completion of the revolution of the hand shaft, the paper is stationary and will not be torn by the descending fingers. At this time also the teeth of the gear l5 are clear of the gear 31 so that the latter is free from connection with the recording mechanism and can rotate, with a subsequent dispensing operation as previously explained, without moving said mechanism.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a depar ture from the spirit of the invention, as defined by the appended claims.
